Perzy01: Please TRY to straighten out this odd putting habit and for God sake, tighten up the putting grid so we can see how the ball will REALLY roll!
Look past the sarcastic puss that mocked you for your post, Perzy, there's somewhat of an explanation. Your view of the putt depends on what pictures are available for the spot you're at. There are only so many pictures to use and if one doesn't match up exactly with your view, you get the closest. I find that reverse views are pretty close and when you compare them to forward views, it helps.
You can actually scroll through the available pictures by using the L/R arrows next to the camera. Many times you'll find a decent view you can use, just don't expect perfect looks. There's also a putt preview feature in practice rounds that may help you, too. It lets you see the putting line before you putt.
As far as more dots, I agree with you but it was explained a long time ago why there aren't and IIRC, it had something to do with causing meter problems. Not sure I remember that correctly but I do remember WGT's explanation making sense at the time.
